    摘要: An addressing scheme for non-volatile memory arrays having short circuit defects that manages the demand for error correction. The scheme generally avoids simultaneous active driving of the row line and column line of the selected cell during write. Instead, only a single row or column line is actively driven at any one time and all other array lines are left floating. In addition, the number of memory cells accessed from a given row or column during a fetch may be limited. The benefits of the scheme include preventing short circuits from drawing excess currents through the array and limiting the frequency of read or write failures caused by short circuits to a manageable number. In one embodiment, the scheme maintains the demand for error correction to within the error correction capability of a flash controller. Exemplary embodiments include phase-change memory arrays.

    摘要: A phase change memory cells including a memory element or a threshold device is read using a read current which does not threshold either the memory element or the threshold device in the case of both a set and a reset memory element. As a result, higher currents may be avoided, increasing read endurance. A sensing circuit includes a charging rate detector coupled to a selected address line and sensing a rate of change of a voltage on the selected address line.
